To promote the release of Episode III in 2005, Lucasfilm produced this little who's who of the Star Wars Galaxy. The first disc was a pack-in with the UK newspaper The Sun. You had to buy a second paper, News of the world, the following day to obtain disc 2: Villains.
The first disc came in a gatefold, paper sleeve with an empty pocket for the second disc. The second disc came in a single, cardboard sleeve. The same programme was released in much the same manner in Australia, but that release was single-disc only.

Some collector's find tracking down releases such as this a sport. I loathe it.
